DEVICE FOR BEATING EGGS AND WHIPPING CREAM.

Specification of Letters Patent.

Patented Aug. 9, 1910.

Application filed August 19, 1909. Serial No. 513,582.

To all whom it may concern:

Be it known that I, BENJAMIN F. FOWLER, a citizen of the United States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented a new and useful Device for Beating Eggs andVVhipping Cream, of which the following is a specification.

The invention relates to a device for beatincr eggs and whipping cream.I

he object of the present invention is to improve the construction ofdevices for beating eggs and whipping cream, and to provide a simple,inexpensive and efficient egg beater and cream whipper, equipped with anair valve adapted to close on the down stroke and open on the up stroke,whereby air will be forced through the material operated on tofacilitate the beating of the eggs and the whipping of the cream andsimilar operations.

\Vith these and other objects in view, the invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawing, and pointed out in the claimshereto appended; it being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe claims, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawing :Figure 1 is a vertical sectional view of an egg beater.and cream whipper, constructed in accordance with this invention, thedasher being shown in elevation. Fig. 2 is a vertical sectional view ofthe dasher. Fig. 3 is a horizontal sectional view on the line 33 ofFig. 1. Fig. 4 is a detail sectional view, illustrating another form ofthe invention.

Like numerals of reference designate corresponding parts in all thefigures of the drawing.

The device for beating eggs and whipping cream is equipped with a dasheroperating within a cylindrical receptacle 1, and provided with aslightly concavo-convex head 2, having perforations 3 and secured to thelower end of a tubular stem 4:. The lower end of the tubular stem 4 ispreferably secured within a sleeve 5 of the dasher head, but it may beattached to the latter in any other desired manner. The upper end of thetubular stem 4: is connected with a knob or handle 6 by means of a shortinner-tube 7 telescoping within the outer tube and secured at its upperend to the knob or handle and having a limited movement with respect tothe tubular stem, such relative slidable movement of the inner and outertubes on each other being limited by a transverse pin 8, secured to theouter tube and operating in a longitudinal slot 9 of the inner tube. Theinner tube is provided a short distance below the handle or knob withopenings 10, which are uncovered or exposed on the up-stroke to permitthe entrance of air. On the down stroke the openings 10 areautomatically covered to prevent the escape of air, which is forcedthrough the substance operated on, thereby aerating the substanceoperated on and facilitating the beating of the eggs, the whipping ofthe cream and the performance of similar operations. The knob or handleis provided at its lower face with a packing 11 of rubber or othersuitable material, seated within the knob or handle and arranged to beengaged by the upper edge of the tubular stem, whereby an air tightclosure of the upper end of the stem is effected. The tubular stem isopen at both ends and on the down stroke when the upper end of the stemis closed by the packing, the material operated on, splashing into thelower end of the tube, displaces a quantity of air, which passes throughthe contents of the receptacle and, as the tubular stem is cushioned inits reciprocation by the packing, the hand of the operator is relievedto some extent of jar. The packing is preferably provided in its lowerface with a recess 12 into which the upper end of the tubular stemextends on the down stroke of the dasher. The short tube, which isslidably connected with the tubular stem of the dasher, has its upperend suitably secured within a socket or opening of the knob or handle.

Instead of arranging the short tube withc in the tubular stem, asillustrated in Figs.

1 and 2 of the drawing, it may be arranged on the exterior of the stemof the dasher, as shown in Fig. 4. In this embodiment of the invention,the short tube 13 is secured within a socket 14 of the knob or handle15, a packing 16 being first introduced into the socket 14. The tubularstem 17 telescopes within the short tube and is arranged to engage thepacking to close its upper end. Sufiicient space is provided between thetubes to permit the entrance of air on the upstroke, when the knobor'handle is raised out of contact with the upper end of the stem of thedasher. The short tube is detachably secured on the upper end of thestem of the dasher by means of a resilient catch 18, constructed ofspring wire, or other suitable material and consisting of a stem havingits lower terminal portion bent at right angles and extended through thetubular stem forming a transverse fastening device 19. The upper portionof the stem is bent outward to form a loop 20, and the upper terminal 21is extended inwardly through a slot 22 of the outer tube and through aperforation 23 of the inner tube or stem. The slot 22 limits therelative movement of the inner and outer tubes similar to the transversefastening device 8, heretofore described.

Having thus fully described my invention, What I claim as new and desireto secure by Letters Patent, is

1. A device of the class described provided with a dasher including atubular stem, a handle, a short tube secured to the handle and slidablyconnected with the tubular stem, one of the tubular parts being providedwith an opening, which is covered and uncovered by the other tubularpart, said handle being arranged to close the upper end of the stem onthe down-stroke to prevent theescape of air and movable away from thesame on the up-stroke to permit the entrance of air.

also forming a cushion for the tubular stem.

3. Adevice of the class described provided with a dasher including atubular stem, a

handle, a short tube secured to the handle and slidably fitting thetubular stem and provided in its lower portion with a longitudinal slotand having an opening in its upper portion arranged to be covered anduncovered by the tubular stem on the downstroke and up-stroke of thedasher, means carried by the tubular stem and operating in the slot ofthe inner tube to limit the relative movement of the stem and the saidinner tube, and a packing mounted on the handle and arranged to beengaged by the upper end of the tubular stem to form ,a tight closurefor the same. I

In testimony, that I claim the foregoing as my own, I have heretoafiiXed my signature in the presence of two witnesses.
